AGE-RELATED VOWEL VARIATION IN FRENCH

Résumé

This paper presents a study on the temporal and spectral characteristics of oral and nasal vowels in French read speech, produced by speakers from 25 to 90 years. The study utilizes a set of eight vowel categories and combines classical vowel spacerelated metrics with MFCC parametrization to accurately include nasal vowels. In total 15,375 vowels were analyzed from data from 37 French speakers (20 females, 17 males). Our data showed (a) a slowing down (increase in vowel duration) with age and (b) no clear change in the overall centralization/dispersion of vowels with increasing age. However, for older male speakers, there was a decrease in the variability within vowel categories and a moderate increase in the separation between categories. Additionally, both male and female speakers demonstrated a greater acoustic distinction between oral and nasal vowels with aging.
